Officials at the Tropicana have closed 560 rooms that are believed to have renovations that don't comply with building codes.

On Thursday, hotel managers made the decision to close the rooms in the Paradise Tower to deal with a discovery that plumbing renovations to the rooms are out of compliance, general manager Ron Thacker said.

"We intend to work diligently and in cooperation with local authorities to bring the rooms into compliance as soon as possible," he said.

All other rooms, casino, pool and convention facilities remain open.

Thacker described the problem as being related to plumbing fixtures, but said he didn't have enough details to elaborate.

"We are still assessing it," Thacker said.

He said building engineers and inspectors discovered the problem during a routine annual inspection on Wednesday.

The renovation in question was done in the 1990s and the compliance issue had previously gone unnoticed, Thacker said.

Guests are being relocated to other rooms that weren't affected by the renovation. If there aren't enough rooms in the 1,800-room property to accommodate all the guests, they will be moved to other resorts, Thacker said.

Thacker said midweek occupancy has been low but weekends have been full, meaning the property is likely to lose out on weekend revenue until the problem is resolved.

"We were looking for a pretty good weekend, so yeah, it hurts," Thacker said.

The Tropicana Las Vegas features six restaurants, an 850-seat theater, three pools, more than 1,800 hotel rooms and 61,000 square feet of casino floor space. It opened in 1957. It is currently owned by Tropicana Entertainment of Las Vegas.
